Victorians have one more day to contribute to an inquiry hoping to uncover any poor practices at assisted reproductive treatments such as IVF.

Price and dodgy operators are among the concerns raised about Victoria's fertility treatment sector.

Victorians who have had worrying experiences with assisted reproductive treatments such as IVF have been sharing their stories, as a deadline looms for public submissions to an inquiry.

Assisted reproductive treatment (ART) providers are also being encouraged to recount their experiences with the state's Health Complaints Commissioner.

Submissions for the probe will close at midnight on Friday, with Commissioner Karen Cusack receiving more than 100 since late June.

People using ART have told her they're concerned about price, expectations and adverse events such as ovarian hyper-stimulation syndrome.

They've also flagged issues with the use of 'add-ons' or 'adjuvant' therapies, being procedures or medications aimed at improving the chances of successful treatment.

Mandatory counselling sessions have also been a topic regularly raised in the feedback.

"Consumers are concerned that this counselling can be a 'tick box' exercise and that there is not enough ongoing counselling provided, such as after an unsuccessful treatment when support is needed the most," Ms Cusack said.

Treatment providers have been worried about operators who don't have proper qualifications.

The submissions will form part of a report the commissioner will provide the state government.
